VEHICLE-SPRING.

Specification of Letters Patent.

To all whom itmay concern Be it known that I, DANIEL R. RAYMoNn, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles have invented newand useful Improvements in Vehicle- Sprin'gs, 0f which the followingais'a 'specification. I

This invention relates-to a springmid .particularly pertains to a vehicle zsy-vring and the mounting I therefor.

It is the object :of this inventiontto provide aspring and spring mounting which is especially adapted for :use :on vehicles such as automobiles :and the like to cushion movement between the vehicle .axles and the frame or body.

Another object is to provide a .spring of the above character so constructed and air-- :range'd that the vehicle body will remain substantially on "the normal plane irrespective ofvertical movement of the vehicle axles in relation thereto.

Another object is :to provide a mounting forrai'spring of the semi-'elliptioalgtyp'e which will permit of .elongationwofthe spring on depression thereof :and which on the elongation of the spring will operate :to elevate :the load carried by the :spring in opposition to the tendencyio'fithe load to vmove downward as is the (case of the ordinary semi-elliptic spring arrangements :and which will thus serve tolessenmovmentof :the vehicle body in lrelation :to the axles.

:Another object is .to provide a :slid'able mounting for the ae tremities of "the semielliptic spring, embodying 'T inclined walls on which :the ends of 'tlrefspringnre adapted .to :travel to longitudinally and vertically advance the end portions of the spring in relation to the vehicle axlebn upward movement :of the latter.

A zfurther iohj'ect :iS-itO provide a novel i-roller connection between the ends of the spring :and the :inclined -walls engaged thereby.

Other iobj'ects will i-appear zhereinafter.

The invention is :illustrated :lIl theaccompanying drawings in i which Figure :1 :is a view in side aelevation illus- 'trating'the invention as applied, showing the semifelliptica'l spring as arranged with .its tends -iextending zupwardly and as center connected :to a vehicle r axle andshowingithe 'iinclined spring iengag-inglw allsi as :formed in- :tegral with the zvehicleiiram'e.

Fig. 3 is an enlarged transverse section on the line 3+3 of Fig. 2

showing the construction ofthe roller connection between the spring and the inclined wall engaged thereby. F g. L is a View in sectlon and elevation as seen on the lined-4 of Fig. 3in the direction indicated by the arrows. Fig. r5? is a "view in section and elevation on the line 5-5 of Fig. v1 showing integral with the vehicle frame.

.More specifically, 6 lndicates an .ordinary semi-elliptical spring which may be attached at its longitudinal center either to the vehicle axle or to a vehicle frame in the-manner common in vehicle construction. illustratedin Fig. 1, the spring '6is rigidly secured intermediate its zendszto anaxle 7 and has its extremities turned upwardly to en- :gage'the vehicle frame :8. As ,shown in Fig. 2 the spring is secured to vehicle :frame :79 and has its extremities turned downwardly to connect with the axle :10.

intermediate its ends the inclined walls i The essence of the present invention re- :sides in providinganinclined wallat each end-ofithe spring, and aA-slidable'engagement between the springs itIlClztlLG wall. .In;Fi g'.'1 integral with .the

.framei8 whichzframe,is:compo sed:of a-chan- 'neliron as-illustratedin Fig. 5, having one of its side portions 11:,removably secured to the top portion :of the channel by bolts 12.

Formedion the inner faces ofthe side anem- 'bers ofithechannel; are opposed downwardly divergent grooves 13 with which the ends of the springare engaged as later described. he inclined walls :may be formed ion .12 :pair of demountable'Ebrackets 14: as shown in Fig. 3; the adjacent fiLCBSrOflBh-Q bracketsbeing provided with the inclined grooves 13.

' here :the spring is arranged with its ends extending upwardly asin ig.-.1, thegrooves 13 forming the inclined walls before unentioned, -are disposed to diverge downwardly, and where the spring is shown. as :arranged in Fig. 12 with its ends extending downwardly, the, grooves are disposed to diverge In other words, the redirection :of

site the direction of movement of the spring on compression so that the ends of the springs which are normally positioned at the nearest ends of the grooves will be caused to move outwardly in said grooves on compression of the spring.

The connection between each end of the spring and the adjacent. grooves is here shown as comprising a revoluble shaft 15, the ends of which extend into the grooves 13 as shown in Figs. 3 and 5. This shaft 15 is'carried by the end of the spring and is preferably mounted in an anti-friction bearing which consists of a series of anti-friction rollers 16 which are arranged around the shaft 15 and within an annular bushing 17. The bushing 17 is fitted with end walls 18 for holding the rollers 16 in place and through which the shaft 15 extends. The end of the spring is bent to encircle. and firmly engage the bushing 17 as shown in Fig. 4. By thusmounting the shaft 15 it may have rotary movement in relation to the inclined walls of the grooves 13 also to the spring 6 and slidably engaging parts are thus avoided.

Inthe operation of the invention, reference being had to Fig. 1, upward movement of the axle 7 inrelation to the vehicle frame 8 will operate to compress the spring 6 which tends to elongate the span thereof and causes the shafts 15 in its ends to move downwardly on the inclined walls of the grooves 13 which movement of the springs tends to prevent upward movement of the frame 8 with the axle 7 and. to permit vertical movement of the axle without materially disturbing the plane of the vehicle frame. The operation is substantially the same with the arrange- -ment shown in Fig. 2 and upward move- 'ment of the axle 10 in opposition to the spring 6 and frame 9 will tend to elongate the span of the spring causing the ends thereof to rideupwardly on the inclined walls of the grooves 13. It will be seen that an upward impact on the spring by the ve hicle axle tending to elongate the span of the spring, will cause the spring to have a tendency to exert a downward pull on the vehicle body or frame thereby neutralizing the tendency of the vehicle frame to move upward with the axle, thus substantially maintaining the vehicle frame on an even plane irrespective of vertical movement of the axle in relation thereto.

What I claim is:

1. In a suspension device, a pair of spaced parallel plates having correspondingly inclined opposed grooves on their adjacent faces, a second pair of spaced plates formed with correspondingly inclined opposed grooves on their adjacent faces, inclined oppositely in relation to the grooves on the other plates, said grooves having closed ends and parallel side walls, a pair of relatively able connection between the to permit elongation of the span of 4 ter and cause both ends of the spring to move which the ends of the spring are slidably engaged to permit elongation of the span of the spring on movement of the members toward each other. 3. The combination with a pair of relatively movable members, one of which isfitted with spaced divergent guide grooves having parallel side walls, a semi-elliptic spring interposed between said members, and a slidextremities of said spring able with either wallof said 4. The combination with tively movable members,

grooves. a pair .of rela 7 one of which is fitand the guide grooves engage ted with spaced divergent guide grooves, a

semi-elliptic spring interposed between said members, and a slidable connection between the extremities of said spring and the guide grooves, said grooves diverging in a direction opposite the direction of compression of the spring and having parallel side walls. I

5. The combination with a pair of relatively movable'members, spaced oppositely inclined pairs of parallel grooved walls carried by one of said members,'and a semielliptic spring attached intermediate its ends to the other member having its ends slidably engaged between said inclined parallel walls.

6. Thecombination of a pair of'relatively movable members, spaced oppositely inclined grooved Walls carrled'by one of said members, a semi-elliptic spring carried by the other member,

and rollers on the extremities of said spring engaging the inclined walls,

- forming a slidable connection and co-acting with the walls on compression of the spring the lataway from the wall carrying member.

7. The combination with a pair of relatively movable members, a semi-elliptic shafts mounted in said grooves revolubly connected to the ends ofthe spring.

. 8. The combination with a pair .of relatively movable members, a semi-elliptic spring carried by one of said members, brackets formed on the. other member extending on opposite sides of said spring near its ends, inclined guide grooves on the adjacent faces of each pair of brackets, shafts mounted in said grooves revolubly connected to the ends of the spring, and anti-friction rollers interposed between said shafts and the spring.

9. In a suspension device, a pair of spaced parallel plates having correspondingly inclined opposed grooves on their adjacent faces, a second pair of spaced plates formed with correspondingly inclined opposed grooves on their adjacent faces, inclined oppositely in relation to the grooves on the other plates, said grooves having closed ends five cents each, by

and parallel side walls, a pair of relatively movable members on one of which said pairs of plates are carried in spaced alinement, a semi-elliptic spring secured at its middle to the other movable member with its ends extending between the plates of each pair of plates, and turnable pins carried on the ends of the spring projecting on each side thereof and terminating in the parallel grooves in position to bear on either side wall of the latter.

In testimony whereof I have name to this specification.
